I have a 1975 Cessna 150 Aerobat.

I want to replace the standard 26 gal (13 per side) fuel tanks
with the optional 38 gal (19 per side) long range fuel tanks.

I don't know if the plane will retain it's aerobatic abilities since many
STC's remove that from the plane upon modification. However, if you want
the original design you'll have to find a pair of Cessna Wings to do it,
not easy. There are the Flint Wing Tip tanks out there, it's very very
expensive to do however.

Go to the Cessna 150 -152 group on egroups.com and search the archives and
you'll find it. I have a friend named Wayne in Tx that installed them on
his 150/150 and loves them, but rarely fills them because it's almost
impossible to fly legally with all the tanks full unless you're a real
lightweight pilot and flies solo, but if you are, they're good.

They work by a mechanical fuel transfer, i.e. you flip a switch after
flying so long and transfer the fuel from the tip to the mains. If you
pump to long it goes out the overflow tube.

Near as I remember him saying, it's several thousand to do the
modification.
